Man created God. Thousands of years ago, it was difficult to understand many things that happened, and so to explain it all, man decided that a superior being was the cause. It was a logical conclusion for them. It encompassed everything that they as man could NOT do. Earthquakes, rain, thunder and lightning, wind, all of these things needed an explanation for man's curious mind.

Of course, then, when other things happened, God was the cause. The concept built up until it was a major being.

Then along came Christianity, which is all based on complete lies (although they didn't consider them lies at the time, the Gospels were never meant to be taken as literal truth). Although Jesus was very likely real (the earliest historical mention is in Flavius Josephus's Antiquities of the Jews, written in 94ad (although there is suggestion that it may be a forgery). Others mentioning him include Pliny and Thaddeus. But the Gospels were made up, mostly by Matthew and John. Mark's Gospel, written in 70ad does NOT mention the birth of Jesus, he appears at the age of 30 when he meets John the Baptist. And the resurrection is not in Mark at all. Before anyone says that it is, I will point out that the resurrection in Mark was added a long time later to make it consistent with the other Gospels. Jesus, in real life, was a revolutionary who wanted the overthrow of Rome, which is why he was crucified for sedition. Matthew created the Biblical version of Jesus around 60 years after the crucifixion, and based the story on the prophecy of a man who would lead the Jews to the Kingdom of God. The Kingdom became Heaven, even though the REAL Kingdom of God was actually just Palestine, which according to legend, was given directly to the Jews by God. Because Jesus was executed before he could do this, Matthew had to have him come alive again, and so created the resurrection story. As the leader would, according to the prophecy, be born in the city of David (Bethlehem), the birth of Jesus was placed there, even though Jesus was actually born in Nazareth. Although the census that took place was real, no-one had to move to their town of birth. That makes no sense at all. The census was to aid taxation, so how would you know what they owned (house size, oxen, slaves and servants, etc) if they were not there? Apart from that, Nazareth was in Galilee, and so the census wasn't taken there anyway. The prophecy also stated that the Savior would emerge from Egypt, so the Slaughter of the Innocents, where every male child two and under was killed to prevent the birth of the Savior. This NEVER happened, there is no record of it. However, by creating it, and having Jesus and his family flee to Egypt for safety, you now had him 'emerge from Egypt' later. This is typical of the Bible, base the stories on half truths, legends, prophecy, and outright lies, to form a tale. As I said, these are not 'lies' as such, they were never meant to be taken as true stories.
